A holt l1 is threaded into standard iieair its The holt il vis provided with :inv suitiihle grip o r handle l2 et its outer end, sind on` its iiiiier end, there .is l'ormed :i tapering, penetrating pointl 13, Fig. 3. The tupering point l 3 is iiorinully sented within ii socket or aperture lorined in disk 14, which disk li. is secured :it the small end of the slotted core 15. A small disk lli is iixedlv secured to the threaded holt 1], neu-r theI '.lhe. dislilo is norniu-lly retained against the disk i4, when the core 15 is in the position shown in l `igs. -1 und '3, thereby preventing seid pointed end l3`i'rom being forced through or too fai' into the shitlOO - anges 19, 19, Fig. 2.

ted core 15. The pointed end 13 is formed substantially conical-sha ed, so thatl the slatted core 15 is permitte to revolve freely thereon.

At the opposite end-of the platform 2 to that carrying the standard 6, is secured a removable head block 17, which I will preferably hereinafter designate the "primary standard, While the, adjustable standard will be dcsignated,the auxiliary standard. The primary standard 17 is provided with a vertical body whichA is provided preferably with a pair or vertical bearing extensions or portions 18 at its upper end, wliileits base is referably formed with laterally extending The flan'es 19 are provided with apertures, and sui table removable fasteningmeans, as bolts 20, 20 are positioned Withinieach of said flanges 19y for fixedly securingthe removable primarystandard in a stationary position. it is not necessary to adjust the primary standard, as is the case with the auxiliary standard 6.

Removable caps 21 are positioned upon the bearing extensions 18 and secured to said f extensions by any suitable fastening means. J ournaled between the caps 21 and the extensions 18 is rotary shaft 22. The shaft 22 is provided at its inner end with a squared shoulder`23, which is normally positioned Within' -a y similarly constructed aperture formed in the disk 24, which disk 1s posi-w tioned inthe largest end of the slatted core 15. By reason of the squared structure of the inner end 23 of the shaft 22 and the recess or disk 24, when rotary movement is imparted to the shaft 22, similar' movement will be im arted to the slatted core. A disk 25 is fixe y secured to the shaft 22 contiguons to the squared end 23 and is adapted, like disk 16, to engage a disk, iwhen'the core is inits rormal position, Fig. 1. A shoulder 26'is formed upon shaft 22, and is of greater diameter than the journals or apertures formed in the primary standard 17 by means of the extensions 18 and capsv 21. .The shoulder 26 prevents outward movement of shaft 22 upon .the primary standard 17. Ro-

tary movement may be imparted to said' shaft 22, by applying'power to the belt Wheel 29, Whiclrwheel is fiXedly secured near the outer end of shaft 22, or if it is desired, an ordinary crank shaft, shown by dotted lines 30, may he secured to the squared, outer end 31 of shaft 22. It will be obvious that either mechanical or manual power may be utilized for rotating the slatted core.

If it is desired to remove the slatted core 15 from the threaded bolt 11 and shaft 22, this may be accomplished by threading the bolt 11 outward upon the auxiliary standard 6. If it is desired to position the slatted core 15 upon lbolt 11 and shaft 22, the same may be do'ne by rotating said bolt sucient to permit the`core tvpass between the inner ends of the liolt f1 and shaft 22, and Yafter .one end of the core and the smaller di.-.k 14

secured atthe other end of the core. An intermediate disk 33 is positioned 'within the slatted core, preferably near the middle thereof. The slats 32 are fixedly secured to the disks by any suitable lfastening means, as

for instance, nails 34. After the plastic material, las for instance, cement, has been placed` u on the slatted core, as hereinafter describe and if it is desired to remove the core with its coating of cement, and simport the same until the cement has completely dried, this can be acconrlished by'drawing the longitudinally slidinv iandles 35 outward through the medium'of their hooked ends 36.

There is a handle 35 positioned in the slatted core, at each ofits ends. ,Blocks 35 are secured to one of the slats 32 contiguous to the end disks. Each blfick 35 is provided .with a longitudinal groove'S, F ig.-4a, and

each end disk is provided with a transverse groove 37. The handles 35 are slidably seated within the grooves 3G and 37. B f grasping vthe grip or hooked end 36 of the andles,

the handles may be partly or entirely withdrawn.- However, as thefpost or column nears completion, and before the ends are entirely sealed, it is desirable to partly Withdraw the handles"l 35, andwhen the.' post or column is ready to be removed from the machine, th'e operator can lift said post, through the medium of said handle, from said ma' chine and support the post in any suitablev manner, as for instance, shown in Fig. 5. It

will be seen upon referring to this figure 'that y the `dotted lines .designate the handles 35, and said handles are resting u on vertical supports 38. The grips or hoo red. ends 36 of the handles lalso prevent the postl from normally sliding off or being displaced from 4- the supports 38. The peculiar structure of the slatted core for receiving the handles is an essential part of the 'finishedcomposite postA or column.

The wide, upperl ends 4 of the curved supports 3 are provided for supporting a flat gage 39. 0f course, the gage need not necessarily be flat in structure, but I preferably usea flat gage, which is. provided with transverse, elongated slots 4U. Each` slot is formed in said gage 39 contiguous to the curved supports 3; th'e upper end 4 of the curved supports 3 overhanging` thefslatted core Secured to each of the ende 4 ofthe `curved supports 3 is a spring locking member 41. -The locking member 4l is iixedly secured at one end to the curved support 3,

. dries synchronously with the cement, and ob-- 'tening means, as ior instance, screws 44.

ends of the post or column.

and its outer end is*y looped around and provided with a bearing portion 42, which exerts su'llcient pressure against the gage 39 to retain it under normal conditions in an adjusted position. By drawing out on the looped, spring end of the fastening member 4|, the gage` 39 can be slid upward or lowered on the ends 4, so as to control the thickness olthe cement, as it is placed upon the slatted core.` The cement is placed on the core preferably by means of a trowel. Before any cement is Alaced on the slatted core, said core is prefere ly soaked, lor, the reason that if it was not soaked in water before cement was applied, the slats would, undoubtedly, swell as the cement dried, and thereby be liable to crack-the post or column. By soaking or wetting the slattcd core, said core viates the possibility of the post or column cracking. Removably secured at each end of the gage 39, isa ringer 43. The 'linger 43 is secured to the gage 39 by any suitable fas- The gage 39 may be employed for forming posts or columns for different designs, as by reversing the position oF the gage, differently constructed, longitudinal edges may be placed contiguous to the slatted core. Therefore, it is desirable to have the iingers 43 extend upon opposite sides or edges of the gage 39. These lingers remove any eXtra cement'overhanging or projecting beyond the Transverse notches or grooves 45 are formed upon cach of the longitudinal edges of the gage 39, whereby annular beads 46, Fig. 5, are formed upon the post or column. Metallic markers 47 `are seated within cut-out y portions 48, Fig. .4, contiguous to one of the lonffitudinal ed fes, and each marker is preleriibly provided with an elongated slot 49, within which slot is positioned 'a screw, or any suitable fastening means, whereby each n'iarkcr is adjustable within the slot 49, so that annular grooves 5() of dillcrent depths, Fig. 5, may be formed in the post or column.

The base-block mold 51 comprises four sides hinged together, as al 52, and one of said side-s is provided with elongated notches- 52, Fig. ti, withinwhich are adapted to be sccured spring fastening members 53, which members 53 are ixedly secured at one end to one of the4 sides. 'lhese spring locking members secure thc sides in their normal closed position, but it will be obvious that said sides Inav be moved apart when desired. A removable bottom 54 is positioned between the sides of themold, and a tapering extension 55is iiXedly secured to the upper portion of the bottom 54. This extension 55 is preferably semi-spherical in shape, and is adapted to form a similarl constructed recess in the lnishcd base-bloc 56, Fig. 8.. A top plate 57 is provided with a central opening 58. The opening may be round, as shown in Fig. 7, or may be, preferably, squared at the option of the constructor. The plastic material is placed in the mold and tamped, and then the plate 57 is placed upon the sides and the opening 58 is filled. When it is desired to place the green block upon a support and again use the mold 5L, this can be accomplishcd by inverting the mold upon the top plate 57, removing the bottom 54, and again reversing the position ol' thc mold upon a suitable pallet. Subsequently, the top plate 57 may be removed, and then the vhinged sides.A lt is desirable, however, to [orm a base-block with a sphere 59 positioned within the semi-spherical recess formed by the eX- tension When the buse-block is in use, the lower portion ol the sphere 5S) is positioncd in the semi-spherical recess formed in a support (i0. 'lhe extension l, l'ornied by the aperture 58 in the top plate 57, is positiioned within a similarly :onstructed aperture formed in the base or larger end of the linished post or column. The recess within which the extension (il of the base-block is positioned, is lormed similar to recessjGZ, Fig. 5, which recess G2, is formed in the Vu per end of thel post or column. 56 comprises a body portion provided on its upper portion with an extension 61, and on its lower portion with a sphere 5S). The sphere 5S) is in'el'crably separately molded from the body of the base-block, and is inserted and integrally secured to the body al'- ter the body has been molded and while yet in its green state.

/ fl"hc recess and groove of disk 24 and the recess of disk l-t-assist in securing the plastic coating or shell upon the core of the finished post or column, as the cement will be positioncd therein, and act, when dried, as a'lock .lor the plastic coating or shell.

When the core is coated with plastic mate'- rial, the disks, which maybe of any shape or conliguration, are not covered. It will, therefore, be obvious that arecess or opening, as l'or instance, 62, Fig. 5, Will-be formed in each end of the nished post. Of course, in the present instance, .l have preferably einploycd disks, and have so described the niembcrs 16 and 25. i

In view of the foregoing description, it will The base-b ook llO be understood that primary standard 17 and auxiliary standard 6 must be'spaced apart a suflicient distance to permita vreenjpost' or column to be Avremoved from samev without marrin'g, or otherwise injuring ost or column.
